Same here. In college I wrote for my school's conservative/libertarian paper and there was one point in one of my articles (because I touched on military policy) my editor wanted me to identify myself as a midshipman. Obviously I told her I couldn't do that, but while in civilian clothes I feel every right to express myself, as long as I don't identify myself.
It did drive me nuts, however, because a few people in my battalion didn't remove political pins from their backpacks and such that they carried when they were in uniform. That was crossing the line IMO.
I think the moral of the story is, like pretty much everything in the military, don't be a dumbass and use common sense.
